PowerTOP v2.9 Release

 

We are pleased to announce the release of PowerTOP v2.9.

 

About PowerTOP:

PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode you can use to experiment with various power management settings, for cases where the Linux distribution has not enabled those settings.

PowerTOP reports which components in the system are most likely to blame for higher-than-needed power consumption, ranging from software applications to active components in the system. Detailed screens are available for CPU C and P states, device activity, and software activity. For many years, PowerTOP has been used heavily by Intel, Linux distributors, and various parts of the open source community.

 

About PowerTOP v2.9 release:

This is a minor release enabling support for the 7th generation Intel® Core™ processors based on Kaby Lake microarchitecture and Next Generation Intel Atom processors based on Goldmont Microarchitecture. Other important feature change in this release is that, for Intel cpus we have stopped displaying pstate idle percentage when intel_pstate is enabled. This change will be reflected in the Frequency Stats tab. There has also been a lot of bug fixes thanks to the contributors’ from the open source community.
